246 16. HYPERICACE^. 



" Nottingham Castle " is too suspicious to allow of that 

 province (8) standing unenclosed in the line which shows 

 the area of the species. As the plant grows in Stafford- 

 shire, Cheshire and Yorkshire, it may be expected also in 

 Derbyshire, which is the most likely one of the Trent 

 counties, wherein to find it.

Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England.

Native. Septal. Although I find no recorded locality 

 for this frequent species within the provinces of the Lakes 

 //c«y/v - or West I j t y i t a nds, its existence there seems so very pro- 

 bable that the estimate has been made to include both 

 of those provinces. It is doubtless a scarce species in 

 the North Highlands and Isles ; the name not occurring 

 in my own lists of plants observed in the counties of Ross, 

 Sutherland and Caithness, nor in Balfour and Babington's 

 list of species seen by themselves in the B[ebrides. Ed- 

 mondston gives two localities in Shetland ; the name is 

 quoted in Gillies's manuscript Flora of Orkney, but only 

 on authority of Lowe's list; and by the Rev. G. Gordon, 

 the species was observed at Rosehaugh, in Ross.
